Water tank sealing in Al Shati Jeddah
Al Shati is a coastal quarter on the Jeddah Corniche directly on the shore with large hotels, luxury villas and commercial shops. Tanks here face very high water pressure because hotels need vast water volumes around the clock. Salty sea air penetrates fine cracks and causes rapid internal erosion and old tanks show severe leaking around entries and joints.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Shati
Buildings here range from twenty to forty years old and tanks face very high humidity and continuous sea salt. Leaking and erosion are visible on most tanks. The method is set out in full on the full Water tank sealing page.
Massive hotel tanks under continuous pressure
Hotels on the shore have very large tanks serving hundreds of guests daily. Water pressure is very high and water demand runs around the clock. Cracks appear first at entry joints because pressure concentrates on these weak points.
Sea salt and continuous salty humidity
Shore air carries constant salt and humidity reaches eighty or ninety percent year-round. Salts enter through fine cracks and react with cement and steel, causing very rapid erosion.
Tanks on high roofs exposed to wind and salt spray
Hotels and luxury villas are tall structures and tanks sit on high roofs. Strong winds from the sea carry salt spray that hits tanks directly. Salty water finds cracks and enters the tank.
Al Shati on the map
Al Shati sits about 2.5 km from Al Nahdah and about 4.5 km from Al Naeem.

A coastal quarter on the Jeddah Corniche bounded inland by King Abdulaziz Road, with Al Salamah and Al Zahra to the east and Al Murjan to the north. Large hotels, luxury villas, shops and the open-air Al Shati Market front the shore.
Cracking in the wall
Intensive inspection for salt erosion on all tank walls reveals the extent of damage from continuous sea salt.
The floor to wall joint
Assessment of rust and corrosion in reinforced steel, especially around entries and joints, determines whether full repair is needed.
The condition of the old lining
Checking cracks and pits from salt erosion determines whether core structural foundations are compromised.
Sediment and scale
Measuring protective coating thickness and its effectiveness in shielding from sea salt.
The pipe entries
Verifying salt and mineral deposits on the tank floor after drainage indicates tank age and damage extent.
The hatch and the vent
Checking water quality for salt, minerals and bacteria after full repair and disinfection.
How we work
-
1
Inspect with the tank empty
We drain it and read the surface dry: whether the water leaves through a crack, a joint or a pipe collar, and what the outer face of the wall and the ceiling below are telling us. A level test with the valves closed separates a leaking tank from leaking pipework.
-
2
Clean and prepare the substrate
Sediment out, a high pressure wash, the loose old lining and the weak surface layer of the concrete taken back, then dried. The material grips sound substrate and nothing else.
-
3
Make the cracks and joints good
Cracks are chased out and filled with a repair mortar, a cove is formed where the floor meets the wall, and every pipe collar is treated on its own.
-
4
Lining, fill test, sterilisation
Successive coats, each run across the one beneath it, on the face the water touches. Then a full cure, a fill with the level watched, and sterilisation with the first fill run to waste before the tank returns to use.
What water tank sealing includes
-
Finding where the water leaves
Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.
-
Draining and sediment removal
The last of the water and the settled layer on the floor come out, because a lining does not stick over sediment.
-
Cracks and joints made good
The crack opened and filled, a cove formed at the floor to wall junction, and each pipe entry worked separately.
-
Lining coats on the water face
More than one coat, each crossing the one below, in material made for drinking water tanks rather than roof waterproofing.
-
Curing, fill test and sterilisation
The material is left to cure, the tank is filled and the level watched, then sterilised and the first fill run to waste. How long the cure takes follows the material and the weather, and we tell you before the date so you can plan around the supply.
-
A follow-up level check
We come back once it is in service to read the level and check the outer face, because any remaining loss shows up then rather than on the day of the work.
The character of Al Shati
Coastal area: high humidity and salt air through the year
Al Shati is purely coastal with giant hotel and luxury villa chains holding massive tanks under very high water pressure. Continuous sea salt and salty humidity mean repair requires special salt-erosion protection.
Questions about this district
Why do Al Shati tanks erode faster than hotel tanks inland?
Direct sea salts, very high humidity and severe water pressure from hotels all combine to cause rapid erosion.
Do large hotel tanks need more repair than villas?
Yes. Hotels have much higher water pressure and heavier use, cracks appear much faster.
What causes erosion to accelerate this rapidly in such a coastal setting?
Sea salts react with cement and steel internally and continuous salty humidity weakens structural integrity.
Does water from a damaged tank become salty?
It may contain salt traces but the tank itself is what erodes. The water may be safe but the tank structure is weak.
Does repairing a large hotel tank take a long time?
Yes. Large tanks need complete drainage, full coating removal and comprehensive repair, which takes several days.
How do we protect a new tank in Al Shati from rapid salt erosion?
Special salt-resistant protective coating is applied inside and regular inspections plus continuous water treatment prevent major problems.
How much does water tank sealing in Al Shati cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Shati.
